chromatin
coils up into chromosomes during mitosis
Gene

Interphase
The cell grows, performs its normal functions - metabolism, and prepares for division;
sister chromatids
Identical copies of a chromosome
Centromere
Area where the chromatids of a chromosome are attached
Prophase
first stage of mitosis, chromosomes become visible, chromatin condenses into chromosomes, nuclear envelop breaks down and spindle starts to form
Metaphase
Chromosomes line up in the middle of the cell
Anaphase
Phase of mitosis in which the chromosomes separate and move to opposite ends of the cell
Telophase
After the chromosome seperates, the cell seals off, Final Phase of Mitosis.
Cytokinesis
